Abstract

In one embodiment, a method for managing thermal dissipation in a display of an information handling system includes: emitting, by a light source of the display, a visible light within the display, the visible light associated with a heat within the display; receiving, by an absorption layer of the display, the visible light within the display, the absorption layer coupled to a display cover of the display; absorbing, by the absorption layer, a portion of the visible light comprising a light leakage from the display; absorbing, by the absorption layer, a portion of the heat within the display; and transferring, by the absorption layer, the portion of the heat into the display cover.

Claims (67)

1. A method for managing thermal dissipation in a display of an information handling system, the method comprising:

emitting, by a light source of the display, a visible light within the display, the visible light associated with a heat within the display;

receiving, by an absorption layer of the display, the visible light within the display, the absorption layer coupled to a display cover of the display;

absorbing, by the absorption layer, a portion of the visible light comprising a light leakage from the display;

absorbing, by the absorption layer, a portion of the heat within the display;

transferring, by the absorption layer, the portion of the heat into the display cover;

identifying, by a thermal controller of the information handling system, that an operating mode of the display has been modified from a normal mode to an enhanced mode, the enhanced mode causing the light source to emit the visible light with an increased brightness;

identifying, by the thermal controller, a transition period associated with the enhanced mode, the transition period comprising a period of time in which the operating mode changes from the normal mode to the enhanced mode;

determining, by the thermal controller, a modified transition period associated with the enhanced mode based on the transition period and a temperature associated with the increased brightness; and

causing, by the thermal controller, the operating mode to change from the normal mode to the enhanced mode based on the modified transition period.

2. The method of claim 1 , further comprising:

transferring, by the display cover, the portion of the heat away from the information handling system.

3. The method of claim 1 , further comprising:

receiving, by a reflective layer of the display, the visible light within the display, the reflective layer coupled to the absorption layer; and

reflecting, by the reflective layer, the visible light within the display.

4. The method of claim 3 , wherein the reflective layer is a composite comprised of an acrylic polymer and a granulated silver.

5. The method of claim 1 , wherein the modified transition period comprises a longer period of time than the transition period, the longer period of time allowing the operating mode of the display to change from the normal mode to the enhanced mode without the temperature associated with the increased brightness causing a delamination of the display.

6. The method of claim 1 , wherein the enhanced mode comprises:

a high dynamic range (HDR) mode; and

a high refresh rate (HRR) mode.

7. The method of claim 1 , wherein the absorption layer is a composite comprised of an acrylic polymer and a granulated graphene.

8. The method of claim 1 , wherein the light source of the display is comprised of a plurality of organic light-emitting diodes (OLEDs).

9. An information handling system, comprising:

at least one processor; and

a display including:

a display cover;

a light source configured to emit a visible light within the display, the visible light associated with a heat within the display; and

an absorption layer coupled to the display cover, the absorption layer configured to:

receive the visible light within the display;

absorb a portion of the visible light comprising a light leakage from the display;

absorb a portion of the heat within the display; and

transfer the portion of the heat into the display cover; and

a thermal controller configured to:

identify that an operating mode of the display has been modified from a normal mode to an enhanced mode, the enhanced mode causing the light source to emit the visible light with an increased brightness;

identify a transition period associated with the enhanced mode, the transition period comprising a period of time in which the operating mode changes from the normal mode to the enhanced mode;

determine a modified transition period associated with the enhanced mode based on the transition period and a temperature associated with the increased brightness; and

cause the operating mode to change from the normal mode to the enhanced mode based on the modified transition period.

10. The information handling system of claim 9 , wherein the display cover is configured to transfer the portion of the heat away from the information handling system.

11. The information handling system of claim 9 , wherein the display further includes:

a reflective layer coupled to the absorption layer, the reflective layer configured to:

receive the visible light within the display; and

reflect the visible light within the display.

12. The information handling system of claim 11 , wherein the reflective layer is a composite comprised of an acrylic polymer and a granulated silver.

13. The information handling system of claim 9 , wherein the modified transition period comprises a longer period of time than the transition period, the longer period of time allowing the operating mode of the display to change from the normal mode to the enhanced mode without the temperature associated with the increased brightness causing a delamination of the display.

14. The information handling system of claim 9 , wherein the enhanced mode comprises:

a high dynamic range (HDR) mode; and

a high refresh rate (HRR) mode.

15. The information handling system of claim 9 , wherein the absorption layer is a composite comprised of an acrylic polymer and a granulated graphene.

16. A system for managing thermal dissipation in a display of an information handling system, the system comprising:

a display comprising:

a display cover;

a light source configured to emit a visible light within the display, the visible light associated with a heat within the display; and

an absorption layer coupled to the display cover, the absorption layer configured to:

receive the visible light within the display;

absorb a portion of the visible light comprising a light leakage from the display;

absorb a portion of the heat within the display; and

transfer the portion of the heat into the display cover; and

a thermal controller configured to:

identify that an operating mode of the display has been modified from a normal mode to an enhanced mode, the enhanced mode causing the light source to emit the visible light with an increased brightness;

identify a transition period associated with the enhanced mode, the transition period comprising a period of time in which the operating mode changes from the normal mode to the enhanced mode;

determine a modified transition period associated with the enhanced mode based on the transition period and a temperature associated with the increased brightness; and

cause the operating mode to change from the normal mode to the enhanced mode based on the modified transition period.

17. The system of claim 16 , wherein the display cover is configured to transfer the portion of the heat away from the information handling system.

18. The system of claim 16 , wherein the display further includes:

a reflective layer coupled to the absorption layer, the reflective layer configured to:

receive the visible light within the display; and

reflect the visible light within the display.
